At IOMAC 2025, we proudly build upon the legacy of OMA and venture forward to explore new avenues of research and applications. The theme, “OMA and beyond,” highlights that OMA is more than just a technique for modal parameter estimation; it is an essential instrument in civil, mechanical, aerospace and geotechnical engineering for fusing data with models to procure digital twins, physics-based machine learning of complex system dynamics, monitoring linear and nonlinear systems, among many more applications.

Program overview
